'sPEcIFIoATIoNrormin part of Letters Patent No. 692,518,.dated February4, 1902.

Application filed February 15I To all whom, zit may concern:

Be it known that we, FRED S. JAOKS and .WILLIAM D. JACKS, citizens ofthe United- States, residingin the city and county of San Francisco,State of California, have invented an Improvement in Carburetors; and wehereby declare the following to be a full, clear, and exact descriptionof the same.

Our invention relates to an apparatus which is designed for themanufacture of gas from hydrocarbon or like liquids from which theinflammable gas or. vapor can be produced.

It consists of the parts and the constructions and combinations ofparts,which we will hereinafter describe and claim. I

Figure 1 is an elevation of the machine, parts shown in section. Fig. 2is a vertical section through the valves controlling the flow of wa ter.Fig. 3 is adetail of the generator and its connections.

As shown in the present drawings, A is a gasometer-bell adapted. to riseand'fall ina tank B, containing Water, in which the lower which forms aseal in which the. bell A' rises and falls as the gas is increased ordiminished within'it. 1

2 is a pump, which donsists of a hollow eylend, said cylinder beingadapted to rise and fall within a tank 3, its lower end being submergedbeneaththe.watercontained in the tank 3. 'In line beneath the center ofthetank 8 is a hollow cylinder 4, in which a plunger 5 extending abovethe fits, and the plunger-rod 6 extends from the plunger or pistono upthrough a tubular-connection 10 with the bottom of the cylinder 3, andits upper end is connected with the top of the bell 2, so that when thepiston is forced up by pressure it raises the hell 2, and when allowedto fall the bell willsink by gravitation. vBy means of a suction-pipe 7,to be here after described, air and gas are drawn into the hell 2 fromthe carbureter 8, with which the pipe connects, and ,when the bell sinksthe gas is forced out through the same pipe into the 'carbureter, andthence through a conducting-pipe 9 into the gasometer-bell A. A tube 10surrounds the plunger-rod 6, this tube surface of the Water in the tank3, and a second tube 11 of larger di- 1'901. SeflalNo- ILMO. (No model.)V

ameter has its upper end fixed to the top of the bell 2 and extends downover the tube 10,

caping around the plungerrod. Parallel with and adjacent to the cylinder4 is an air-pump cylinder 12, having within it a plunger 13,

and the rod .14 is connected by a cross arm or .FR'ED soAoKs AND WILLIAMD. JAoKs, on SAN FR Norseo, CALIFORNIA;

forming-a seal or lockto prevent any gas esbar'with a rod 15, whichextends up'through I the tank 3 and is connected with the top of thetank in a similar manner to the rod 6. It also has similar inclosingtubes 10 and 11 toaetasagzeal...

Water under pressure is admitted into the lower part of the hydrauliccylinder 4 through a pipe 16, and the water is admitted and exhausted'by means ofvalves 17 and 18, which i are connected by their stems19.with an (30- centric 20,1which is rotatable and operates so that whenone valve is opened the other is closed. One of these valves,-as 17,controls the inlet through a pipe 21 from-any source of supply. Theother, as 1:8,controls the outlet through a' pipe, as at 22. Thesevalves are situated one upon each sideof a central opening in thevalve-chamber,which connects with the supply-pipe-lti, leading to the-cy'lin der 4,'as previously described; J

23 is an air-chamber to steady the pressure and relieve the shock ofwater as it enters and leaves.

The shaft 20. of the eccentric 20 extends out through one end of thecentral portion or,

'the device containing the eccentric 20 and has upon it theloosely-turnable arms 24 25. The arm 25 is connected by chains 26 withthe rod 15, one of these chains extending up-"- vwardly above the centerline of the shaft and -the other downwardly. v I r The operation willthen be as follows: If the piston or plunger 5 is at the bottom of itscylinder 4,- the inlet-valve 17 will beopened and the outlet-valve 18closed by the turning of the eccentric sufficient to produce theseresults. The water under pressure passing through the admission-pipe21,thence through the passage in the upper part of the valvechamber, andthence out through the pipe 16 enters the bottom of the cylinder 4 andforces the plunger 5 upwardly. This acts through its rod 6 to lift thehell 2 and produce a vaeuum within it above the water. The vacuum.

thus produced continues through the pipe 7 and into the carbureter 8,andthis draws the liquid from the measuring-tank 27, through a passage28, into the carbureter-chamber8, at the same time an air-inlet valve at29 is opened, so that a suitable proportion of air may pass in throughthis valve and into the carbureter. The upward movement of the bell actsupon the rod 15,.thus forcing theweight'upon it, will have passed thecenter.

As these arms turn loosely upon the shaft they will not act to move theshaft or to change the position of the valves 17 and 18 until theweighted arm 24 falls and strikes one of the pins 33,which project fromthe eccentric-shaft. The weight striking this pin will then suddenlyturn the eccentric and reverse the position of the valves, closing thevalve 17 and opening the valve 18. t This shuts off a supply of waterthrough the pipe 21 and opens a discharge from the pipe 16 through thepipe 22.

" 'then causes the'plunger 5 to sink and with it The weight of the hell2 or any additional weight which may be placed-upon it the bell. Thewater in the cylinder4 will be forced out through the dischargepipes, asbefore described, and the gas which has been drawn throu'gh the pipe 7by the upward movement of the-bell 2 will now be forced back through-thecarbu reter8, thence through the pipe 9-, and into the gasometer-bell A.

Each reciprocation of the parts of the appa-' ratus will produce as'imilar action, and the amount of gas itrthe gasometer will be renewedat each operation.

The pipe 28, leading from the measuringtank 27, extends up into the tankto a point which is above the level of the liquid'therein, and its upperend is open. Asecond pipe 34, closed at the upper end and of larger diameter, fits down over this pipe 28, extending to near the bottom of thetank, and this forms a passage between the two, so that any pressureupon the surface of the liquid caused by direct pressure or by vacuumthrough the carbureter willcause the liquid to flow up in the pipes 28and 34, and thence down through 28 to the point of discharge. The pipe34 may be raised or lowered by means of a screw 35, connecting with itsupper end and turnable in a suitable threaded nut, as shown. Thus thedischarge end or the pipe 34 may be raised or lowered with relation tothe bottom of the measuring-tank. A check-valve is connected with themeasuring-chamber through a at 40, and thisiserves to regulate thepressure of air within t tank 31.

41 is a check-valve in the pipe 30 to prevent the return of air-when thepressure through the pipe 30 is reduced. This checkvalve may be similarto the valves above de scribed or of any suitable or well-knowncharacter, and a similar valve is connected with the air-inlet pipe 29,as shown.

An overflow-pipe is located at 42', contiguous to the tanks B and 3, and'a pipe 43 con-. nects the tanks B and 3, and. through this the waterisallowcd to pass from one chattiber to the other in case the waterrises higher in either one than'the other. Drain-cocks are connectedwith the waste-pipe, as shown at 44, for the removal of surplus waterfrom the tanks or the overflow 42.

Any suitable or well-known form of car bureter may be employed. In thepresent arrangementwe have shown acarbureter as havingspirally-disposed-plates 46 in the form of a coil or coils extendingbetween the top and bottom of the carbureter-chamber, and in the spacebetween these coils are loosely wound ropes or equivalent masses offibrous absorbent material 47 The inlet-pipe may deliver into the outerpart of the coil, as shown, and the outlet-pipe discharge from thecenter, so that the air drawn through the hydrocarbon in thecarburetenis continually brought into contact therewith and fullysaturated in passing through. The supply of water for the tank 3 is keptup,by such. leakage as passes the piston 5 of the cylinder 4, and as thetube 10 connects with the top of the cylinder this water will bedelivered from its upper end into the tank. The pipe 43 will conveywater from 3 to B and keep B supplied, and the surplus willdischargethrough the overflow-pipe 42. Both-g'asometer and 1e pipe 30 and in thegasolenepump-bellsA and 2 are guided in their rise v and fall byvertical central rods or equivalent tubes, as at tier 6. gasolene orequivalent hydrocarbon through the carbureter and its vaporization causesuch a reduction of temperature that freezing and stoppage will takeplace unless there is some means to prevent it. This means is providedin our device by the tank 3, containing a large body-of water whichraises the temperature of the vapor or gas which is drawn through it bythe upward movement of the bell 2, and when this gas is forced throughthe carbureter and into the gasome- The passage of the ter by thedownward movement of the hell 2 its slower movement and contact with thewaterand the slight compression will prevent its becomingdetrimentallycoldz' The measuring-tank has within it a float 27, and atube 27" extends upwardly from the Heat, open at the top and closed atthe bottom. This tube contains mercury, and the end of the fixedconducting-pipe 32 extendsinto the tube 27. hen the floathasrise'n sothat the mouth of the tube is submerged in the mercury, further supplyto the measuringtank and carbureter is cut off, and when the thesiphon-pipes 28-and 351, as previously de:

scribed.

\ 48 is a vacuum relief-valve connecting with tank 27 to admit air asthe liquid flows out to the carbureten' When the How of gasolenethrough'the pipe I 32 from the reservoir 31 is stopped by the mercuryseal above described, the pressure in the reservoir througlnthe ainpipe30 is regue lated by a relief-valve at 40.
